LAMP-CHIMNEY HOLDER.

Specification of Letters Patent.

Patented Dec. 31,1918.

Application filed February 9, 1918. Serial No. 216,260.

To all whom it may concern Be it known that I, AMANDA A. Hn ivnn- SON, a citizen of the United States, residing at Delavan, in the county of Faribault, State of Minnesota, have invented certain new and useful Improvements in Lamp-Chimney Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use thesame.

The invention relates to a lamp chimney holding attachment for lamp burners, and more particularly to the class of lamp ohminey holders;

The primary object of the invention is the provision of a holder'of this character wherein the construction thereof perm ts thedetachableengagement of the same with the chimney retaining arms of lamp burner, so that the chimney will be held securely in place" upon the burner, without the possibility of accidental tilting of the same or the falling of the chimney from said burner. 7

Another object of the invention is the provision of a holder of this character wherein auxiliary clamping members or cheeks will engage the neck of the chimney when mounted in the burner and engaged by-the resilient arms or fingers upstanding from the base of the burner, so that there is n possibility of the lamp chimney becoming accidentally detached from the burner, and the said chimney will be permitted to expand and contract without the possibility of the breakage thereof-resultant from the bindingactioii of the holder when carried by the burner.

A further object of the'invention is the provision of a holder of this character, which can be readily mounted upon the lamp burner and detached therefrom and also will permit the placing of the chimney in position upon the burner or its removal therefrom.

A still further object of the invention is the provision of a holder of this character wherein the clamping action of the resilient fingers on the lamp burner is augmented so as to securely retain the lamp chimney in place thereon'and to avoid the accidental working loose of the lamp chimney when in position upon the burner.

A still further object of the invention is.

the provision of a holder of this character which is extremely simple in construction, thoroughly reliable and efiicient in its purpose, strong, durable and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction,combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto ap pended.

In the accompanying drawing Figure 1 is a side elevation of the lamp burner showing, a chimney held in place thereon by the holder constructed in ccordance with the invention,

Fig. 2 is a'sectional view onthe line 22 of Fig. 1 looking in the direction of the arrows, v

Fig. 3 is a perspective view of the holder detached.

Similar reference characters indicate corresponding'parts throughout the several views in the'drawing.

Referring to the drawing in detail, A designates generally the burner, which as usual is formed with the circular shaped base'5 having rising therefrom at its peripheral edge a plurality of resilient fingers or arms 6, which slightly converge upwardly and have their upper ends inwardly curved as at 7 for positive frictional engagement with the neck 8 of a lamp chimney 9 which is of the ordinary well known'construction- The fingers or arms 6 are spaced the desired distance apart, as usual and serve toretain the lamp chimney 9 in place upon the lamp burner in the ordinary well known manner.

The lamp chimney holder comprises a plurality of comparatively short coiled .convo luted retractile springs 10 and located between the adjacent ends of these springs are clamping plates 11 constituting gripping cheeks, the plates being preferably outwardly bowed to a slight degree to assure positive gripping action on the neck of the chimney 9 in a manner hereinafter fully described.

Each plate 11 is preferably of rectangular shape and is formed at its opposite longer edges with opposed ears 12, which are folded on themselves to provide eyes 13 in which are loosely engaged the terminal coils of convolutions of adjacent springs, 10 and in this manner plates and springs are loosely connected to each other plates 11 to that one end portion at one side of the cars 12 is longer than the other end portion at the opposite end portions of the plates 11 are disposed downwardly in the direction of the base 5' of theburner A when the holder is applied thereto for securely retaining the lamp chimney 9 in place upon the burner. v

The cars 12 on the plates ll'attheir extremities overlap each other so as to close the eyes 13 to prevent the accidentaldisengagement of the terminal convolutions of coils of the springs 10 from the plates 11 in the use of the lamp chimney holder.

In the application of the lamp. chimney holder the springs at the intermediate points thereof are engaged over the fingers or arms 6 on the burner A so that the plates 11 are disposed between the fingers or arms 6, preferably at a medial point therebetween toengage with the neck 8 of the lamp chimney 9 at points independent of the engagement of the fingers or arms 6 therewith. The springs 10 and plates 11 are disposed concentrically of the neck 8 of the lamp chimney 9 and the resiliency of said springs 10 acts upon. the force the same into positive gripping engagement with the neck 8 of the lamp chimney and thereby augmenting the gripping action of thefingers or arms 6 on the burner A upon the said neck 8 of the lamp chimney, so as to firmly and positively hold the lamp chimney in place in the burner, to avoid any possibility of the lamp chimney falling from the burner or working loose therefrom, yet the lamp chimney can be readilyinserted in place in'the burner or removed therefrom as the occasion may require.

The springs10 are of the proper resiliency sov as to avoid any undue binding action upon the neck of the chimney 9 to eliminate the breaking of the chimney due to expansion and contraction thereof, although the said chimney will be firmly held in place upon the burner A and can be readily inserted between the fingers or arms 6 upon the latter and detached at the will of the user.

.Copies of this patent may side thereof and these longer Each of the plates 11 which are normally outwardly bowed are made from suitable resilient material, such as metal, having the required resiliency to exert a pressure against the neck 8 of the lamp chimney 9 to coact With the springs 10 for the firm and positive gripping of the lamp chimney to holdthe same upon the burner.

From the foregoing it is thought that the construction and manner of use of the lamp chimney holder will be clearly understood and therefore a more extended explanation has been omitted. However it is contemplated Within the scope. of the invention to make changes, variations and modifications such as come properly within the scope of the appended claims, without departing from the spirit ofthe invention or sacrificing any of its advantages. 7

What is claimed is 2% 7 w 1. A'lamp chimney holder of the character described comprising-resilient means for encircling a lamp chimney, and platesjcarried on the resilient means at intervals thereof loosely connected thereto with portions of each plate projected above and below the resilient means. a

2. A holder of the character described comprising a plurality of coils or tractile springs, outu'ardly bowed plates arranged between the adjacent ends ofv the springs, and ears formed on opposite sides of the plates and engaged with theterminal coils of said springs for loosely connectingthe latter and the plates together, a

3. A lamp chimney holder of the character described comprising a plurality of coil resilient members, a plurality of plates, each arranged between the adjacent ends of the resilient members, and cars at opposite sides of the plates and bent on themselves to form eyes loosely conected to the terminals of the resilient members. I H a o 1 In testimony whereof, I aflix my signature, in the presence of two witnesses.
